Grassland revolutions in New Zealand: Disaggregating a national story.

The grassland revolution is a national story but the intensification of New Zealand pastoral agriculture was made possible by many changes in farm practice, and application varied within New Zealand. This paper identifies aggregation issues in the narrative and explores their implications for any reassessment of the revolution. Data from six counties are analysed to illustrate some of the varied experiences across New Zealand farm districts. The paper redirects attention to local- and farm-scale studies as a way to investigate the significance of the diverse drivers of pastoral productivity, their timing and effects.
